脚本宝典收集整理的这篇文章主要介绍了php – Woocommerce在结帐页面上获取购物车中特定商品的数量，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
>如果产品#1769和/或产品#1770在客户的购物车中.
>当前购物车中的#1769和/或#1770的数量将决定要显示的自定义字段的数量.
现在我已经通过以下方式处理了#1：
/** * Check to see what is in the cart * * @param $PRoduct_id * * @return bool */ function condITional_product_in_cart( $product_id ) { //Check to see if user has product in cart global $woocommerce; $check_in_cart = false; foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) { $_product = $values['data']; if ( $_product->id === $product_id ) { $check_in_cart = true; } } return $check_in_cart; } function checkout_register_names( $checkout ) { $check_in_cart = conditional_product_in_cart(1769); // Product id 1769 is in cart so show custom fields if ($check_in_cart === true ) { // Display custom fields for 1769... woocommerce_form_field( 'golf_field_one',array( 'tyPE' => 'text','class' => array('my-field-class form-row-wide'),'label' => __('Golfer #1'),'placeholder' => __('Name'),),$checkout->get_value( 'golf_field_one' )); woocommerce_form_field( 'golf_field_two','label' => __('Golfer #2'),$checkout->get_value( 'golf_field_two' )); //etc... } $check_in_cart = conditional_product_in_cart(1770); // Product id 1770 is in cart so show custom fields if ($check_in_cart === true ) { // Display custom fields for 1770... woocommerce_form_field( 'dinner_field_one','label' => __('Dinner Name #1'),$checkout->get_value( 'dinner_field_one' )); woocommerce_form_field( 'dinner_field_two','label' => __('Dinner Name #2'),$checkout->get_value( 'dinner_field_two' )); //etc... } }
以上代码将有条件地显示我在每个产品下设置的所有woocommerce_form_field(),仅当该产品位于客户的购物车中时.
现在,我需要做的是根据购物车中每种产品#1769或#1770的数量显示一定数量的woocommerce_form_field().
因此,如果有两(2)个产品#1769,则应显示两个字段.如果有两(2)个产品#1769和一个(1)产品#1770,则应显示三个总字段(两个用于产品#1769,一个用于产品#1770).
在任何给定客户的购物车中,每个产品最多只会添加四个,因此将每个表单字段包装在if()中并检查以下内容并不是一件大事：
if([quantity of product 1769] >= 1) {
show First woocommerce_form_field()
}
if([quantity of product 1769 >= 2) {
show second woocommerce_form_field()
} //etc...
// Repeat for product 1770...
我尝试添加$qty_in_cart = $values [‘quantity’];在第一个函数conditional_product_in_cart中的foreach(),但似乎不想给我任何东西.当我检查是否(isset($qty_in_cart))时,它没有设置.
我觉得我很亲密,但是我无法弄清楚我错过了什么.任何帮助,将不胜感激.
